Superhard material electroplated grinding wheel abrasive rearrangement and uniform distribution sanding device and method

Abstract

The invention provides a superhard material electroplated grinding wheel abrasive rearrangement and uniform distribution sanding device and method. The superhard material electroplated grinding wheelabrasive rearrangement and uniform distribution sanding device comprises supporting plates and cover plates which are correspondingly arranged up and down, a sanding shaft is arranged between the supporting plates, a grinding wheel base body is fixedly arranged on the sanding shaft, sand covers are arranged between the supporting plates and the cover plates, superhard abrasives are arranged between the sand covers, and the grinding wheel base body is arranged in the superhard abrasives. According to the device, the abrasive density consistency can be improved, quantitative addition of the abrasives is achieved by stipulating the amount of the abrasives, the consistency of pressure in a jig during each time of sanding is guaranteed, a grinding wheel rotates and moves downwards through the characteristic of screw-thread fit, the abrasives attached to the surface of the grinding wheel base body are rearranged, the distribution uniformity of the abrasives is guaranteed, and on the premiseof keeping the total electric quantity unchanged, the consistency of the abrasive density of each grinding wheel is controlled. Meanwhile, the method can achieve one-time sand feeding success, meet the requirement for one-time sand feeding of the electroplated grinding wheel profile, completely eradicate the influence of sand supplementation on the size of the plated grinding wheel and effectivelyreduce the jerk value of the profile of the plated grinding wheel.

Description

technical field [0001] The invention relates to the technical field of superhard material electroplated abrasive tool manufacturing, in particular to a superhard material electroplated grinding wheel abrasive rearrangement uniform distribution sanding device and method. Background technique [0002] In the manufacturing process of electroplated abrasives, the electroplated abrasives with coarse grain abrasives (grain size above 0.1mm) usually adopt the "buried sand method", that is, use less than 0.3-0.6A / dm 2 The current density of the grinding wheel is directly buried in the abrasive, and it is kept for a certain period of time for sand electroplating, and then the excess abrasive is washed away for thickening electroplating. For grinding wheels whose dimensional accuracy is required to be less than 0.005mm and the particle size of electroplated abrasives to be more than 0.1mm, the existing sand embedding method has the following problems: the amount of embedding sand is u...

Problems solved by technology

For grinding wheels whose dimensional accuracy is required to be less than 0.005mm and the particle size of electroplated abrasives to be more than 0.1mm, the existing sand embedding method has the following problems: the amount of embedding sand is uncontrollable, and the density of abrasives electroplated in different batches of the same electricity has large fluctuations; It is difficult to fill evenly during the addition process, and the accumulation density of abrasives at each position is different, which leads to the problem of abrasive agglomeration in the abrasive layer of the grinding wheel; it is difficult to successfully apply sand at one time, and it is necessary to fill the sand-deficient position several times, resulting in large fluctuations in the beating of the grinding wheel profile after plating ; It is difficult to effectively control the consistency and stability of the abrasive layer thickness of the grinding wheel

The above problems have restricted the technical progress of electroplated grinding wheels with high precision and complex profiles, and become a difficult problem in the industry
